Spanish Housing Act and rentals in Valencia 2026: caps, index and stressed areas

The 2023 Spanish Housing Act and its subsequent developments have profoundly changed rental rules in Spain. In the Valencian Community, the situation has its own nuances: not all the region is a stressed area, but there are new obligations for all owners.

If you let a flat in Sueca, Cullera, Tavernes or anywhere in Valencia, this is what you need to know in 2026.

What is a stressed residential market area?

It’s a formal declaration made by the regional government (in collaboration with the local council) recognising that in a specific area, rent is disproportionate to average household income. When an area is declared stressed:

• Large landlords must apply caps to rental prices.
• The Rental Reference Index is mandatory for new contracts.
• Vulnerable tenant protection measures activate.

As of May 2026, Sueca is not declared a stressed area. Several Valencia city districts are (Ciutat Vella, parts of Cabanyal, La Saïdia, Russafa…). This can change: the regional government revises the list periodically and councils can request inclusion.

The Reference Index and the update cap

Regardless of area, all annual rent updates on existing contracts are limited by an INE-published index. The transition phase has ended, and since 2024 you can no longer freely apply CPI.

In 2026 the index is around 2.2-2.5% annually. In practical terms:

• If your tenant pays €650/month, the maximum you can raise at next annual renewal is around +€14-16/month (650 × 2.3% ≈ €15).

This applies to all small landlords, in any area.

Difference between small owner and large landlord

The law distinguishes two profiles:

Small owner (most cases):

• Up to 5 properties owned (or 10, depending on regional interpretation).
• In non-stressed areas: free to set rental price for new contracts.
• In stressed areas: only some restrictions apply.

Large landlord:

• More than 5 properties in stressed areas (or applicable regional threshold).
• Reinforced obligations: mandatory caps in stressed areas, registry data, inspections, alternative housing offers in evictions.

What changes for an owner in Sueca in 2026

If you have a flat for rent in Sueca, El Perelló, Cullera or any non-stressed Valencia town, the practical changes are:

1. Cap on annual update (~2.3% in 2026). No full CPI.
2. Mandatory split of agency fees: in new contracts, agency management costs are paid by the owner, not the tenant. This changed many capture models.
3. Mandatory notification to the Tax Agency of rental data (Form 179 in some cases, Form 180 annually).
4. Mandatory tenant disclosure about property condition, certifications and meters.

Risk if you get it wrong

The Tax Agency cross-references with the tenant. Penalties for:

• Not declaring rent as capital income: 50-150% on undeclared amount plus penalties.
• Raising rent above the index: €600-30,000 administrative, plus refund to tenant.
• Not issuing mandatory certificates: €600-3,000.

Two frequent mistakes we’re seeing

Mistake 1: Raising rent “because I spent on works”. The extraordinary increase for improvements only applies if the work meets strict conditions (not maintenance), is agreed with the tenant, and the rise is capped at an additional 3%. Not a blank cheque.

Mistake 2: Not indexing the contract to the Reference Index in stressed areas. Even as a small landlord, if the area is declared stressed and you sign a new contract afterwards, you must reference the contract to the Index. Failing to do so can mean losing the indexed increase for the coming years.

What to do this year

1. Review the renewal date of your current contracts and apply the index correctly.
2. Check whether your area has been declared stressed (updated list at the Valencian Government → Housing website).
3. Keep mandatory certificates up to date (energy, habitability, ITE for older buildings).
4. Declare correctly rental income in the next tax return — and apply the 60% allowance if applicable.
